Hello,
I am new to the forum and using HP tuners although I have been a master tech for 25 years. I recently bought an old c10 with a 2004 4.8L LS. The guy I bought it from put a tune on it and it runs pretty good. So I am looking for help on three things
1. Advise the attached tune
2. There are numbers that seem way out of wack compared to what I am seeing on line. ( Torque limit vs RPM, PE ramp rate)
3. I am getting a gear hunt happening at 1600RPM at about 50mph
Thank you in advance.
